1823927 - The save/update panel of addressess and credit cards in about:preferences does not update when locale is changed

Status: NEW

(Toolkit :: Form Autofill, defect, P3)

Description

[Tim Giles [:tgiles] | PTO July 3 - July 14]

Attachment: A screenshot showing two overlapping modals. The underlying modal's title says "Saved Credit Cards" while the in front modal's title says "Añadir nueva tarjeta de crédito"

When changing locales, the credit card/address management UI updates accordingly except for one section in the first modal. You can get to this state by the following steps:

1. Install another langpack from https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-central-l10n/linux-x86_64/xpi/ (make sure you select the correct version for your local build)
2. Navigate to about:preferences#privacy
3. Activate the "Saved Credit Cards" button
4. Activate the "Add..." button
5. Open the Browser Toolbox and run the following (replacing the langpack code with the one you installed): Services.locale.requestedLocales = ["es-ES"] (I use Spanish in my case)

Expected result:
All of the credit card/address management UI is updated to the new locale

Actual result:
All of the credit card/address management UI is updated except for the first modal's title. This title does update accordingly if the add/edit modal is not present, so I'm not sure what is causing the localization to fail when the add/edit window is present.
